Fantasy Baseball is buzzing with prospect news, and the Miami Marlins are at the center of the action. While the official call-up hasn't been announced yet, all signs point to left-handed pitching sensation Robby Snelling making his big-league debut very soon. After a dominant start to the 2026 season—posting a 1.86 ERA and a sparkling 0.90 WHIP over 29 innings with 44 strikeouts—Snelling looks like the logical replacement for Chris Paddack, who was recently designated for assignment. The Marlins could have gone with Braxton Garrett, who is already on the 40-man roster, but they've allowed Snelling to shine, and fantasy managers should be ready to add him in redraft leagues.

While Snelling's rise is exciting, the Marlins' handling of another top prospect, Agustin Ramirez, has left fantasy owners scratching their heads. Ramirez, who was surprisingly sent back to the minors, is arguably the most talented hitter in the entire Marlins organization. He combines elite exit velocity with a keen eye at the plate and even some base-stealing ability—a rare mix that gives him tremendous upside. The demotion was supposedly about improving his defense behind the plate, but that feels like a stretch. Ramirez has never been a standout catcher, and swapping him for defensive specialist Joe Mack (while another catcher, Liam Hicks, is hitting well) seems counterproductive.

The real question for fantasy managers is whether to stash Ramirez or move on. Given his raw power and potential, he's probably worth holding onto in deeper leagues. The most likely scenario is that this is just a short reset to get his bat going, and he could return in as little as 10 days. However, the Marlins' insistence on making him a full-time catcher is puzzling. If they would just let him DH or learn first base, his bat would be in the lineup every day. Until that happens, Ramirez's timetable remains uncertain—but his talent is undeniable.

For now, keep a close eye on Snelling's promotion and Ramirez's return. In the world of fantasy baseball prospects, timing is everything, and the Marlins are giving us plenty to talk about.
